Sir Roger Moore has hinted that he would love to appear in Doctor Who or Sherlock.

He tweeted Mark Gatiss, who co-created Sherlock and writes for Doctor Who: "I might be equally wonderful in Dr Who or Sherlock if asked!" after Mark praised the star's "wonderful" performance in 1970 film thriller The Man Who Haunted Himself.

The screenwriter replied: "My life is complete! Will be [in] touch."

Timothy Dalton, Roger's successor in the Bond franchise, appeared in two Doctor Who episodes in 2009 and 2010, where he starred as Rassilon opposite former Time Lord David Tennant in two-part episode The End Of Time.

Doctor Who, which now stars Matt Smith and Jenna-Louise Coleman, is due to return to BBC One for a 50th anniversary special in November.

Jemma Redgrave, who has already filmed her part as the Brigadier's daughter Kate Stewart, told What's On TV: "It's philosophical, it's deep, it's an adventure story and if you're a kid, you're going to be taken on an extraordinary ride.

"It raises all sorts of interesting questions for anyone who wants to go deeper with it. It's funny and then on a sixpence it breaks your heart. It's just wonderful!"

Shooting on the third series of Sherlock, starring Benedict Cumberbatch and Martin Freeman, is expected to resume in the late summer.
